Thousands of water-skating spiders have blanketed a Greek lagoon in a 1000-foot cobweb — and it looks like a scene from 'Lord of the Rings'

A Greek lagoon has been carpeted with 1000-feet long cobwebs, The Guardian reports.

The seasonal phenomenon is caused by mating spiders of the Tetragnatha genus — otherwise known as stretch spiders.

The eerie scene won't last long, though.

A biologist told Greek news outlets that the spiders will soon die off and the webs will decompose without causing any harm to the vegetation.

Arachnophobes, look away.

In a truly "Lord of the Rings"-esque phenomenon, thousands of tiny spiders have carpeted a lagoon in Greece with cobwebs as long as 300-metres (984 feet), The Guardian reports.

Greek camera operator Giannis Giannakopoulos caught the bizarre event on film and also shared some photos with Business Insider.

According to Science Alert, the spiders are likely from the Tetragnatha genus — commonly known as stretch spiders because of their elongated bodies.

The extreme web-spinning happens during mating season for the spiders, molecular biologist Maria Chatzaki from the Democritus University of Thrace in Greece told Newsit.gr.

Apparently, low numbers of mosquitoes this year have created the perfect storm for the mating arachnids: "The spiders are taking advantage of these conditions, and are having a kind of a party. They mate, they reproduce and provide a whole new generation," Chatzaki said.

If you thought you could swim or sail away from these industrious web-makers, think again. Tetragnatha spiders are reportedly small enough and fast enough to run on water even faster than they can on land.

Fortunately, you probably won't need to run away from them. "These spiders are not dangerous for humans and will not cause any damage to the area's flora," Chatzaki said.
